Null pointer exception in simple streaming call
I am trying to use the streaming API to output a file from one of our solrcloud collections. It seems like this should be simple but it keeps throwing an exception.
I tried to use the Solrconsole UI and got farther than with Java or CURL. In the console if I give it a query with a limited result set it worked alright, but times out with a larger set.
I am running Solr 7.7.3 is solrcloud mode. The collection has 2 shards with 2 replicas per shard. Normally we just use the normal solr search, but I needed to dump out all the rows with some filtering applied This is my CURL command
curl --data-urlencode 'expr=search(qt="/export",q="*:*",fl="display_material_number,display_pno,key_brand",sort="display_pno asc",fq="searchmv_sales_org:(2106 OR 7950 OR 0)", fq="-key_product_status:(INTERNAL OR WITHDRAWN)", fq="-facet_country_exclusions:US")
' http://localhost:8983/solr/sial-catalog-material/stream
This is the response:
./stream_materials.sh
{
"result-set":{
"docs":[{
"EXCEPTION":null,
"EOF":true}]}}
When I created a Java program it gave me this stack trace:
Exception in thread "main" java.io.IOException: java.lang.NullPointerException
at org.apache.solr.client.solrj.io.stream.CloudSolrStream.constructStreams(CloudSolrStream.java:389)
at org.apache.solr.client.solrj.io.stream.CloudSolrStream.open(CloudSolrStream.java:278)
at com.sial.solrcloud.streams.SialStreamingMaterials.main(SialStreamingMaterials.java:46)
Caused by: java.lang.NullPointerException
at org.apache.solr.client.solrj.io.stream.TupleStream.getShards(TupleStream.java:133)
at org.apache.solr.client.solrj.io.stream.CloudSolrStream.constructStreams(CloudSolrStream.java:374)
... 2 more
TupleStream.java line number 133 is:
CloudSolrClient cloudSolrClient = streamContext.getSolrClientCache().getCloudSolrClient(zkHost);
In the Solr Console if I change the q parameter to be q="search_material:T1503*" I get some results so I think the expression is close to what I want. I just want all the rows that satisfy the filter queries.
I don't even know where to look. Any help would be welcome.

The raw java API is not supported. You'll need to use Streaming Expressions
which has a lot of documentation.

Not sure if you saw my response. It looks like your request didn't have a

RE: Null pointer exception in simple streaming call
Posted by Webster Homer <we...@milliporesigma.com>.
Is the streaming API still supported?
Or does it just not support sharded solr cloud collections?
I tried following both of these posts:
If I follow this post http://joelsolr.blogspot.com/2015/04/the-streaming-api-solrjio-basics.html I get a null pointer doing exactly what was done here
If I follow this post https://lucidworks.com/post/streaming-expressions-in-solrj/ Nothing happens
Streaming could be useful if it worked and was properly documented.

I think you're just missing the collection as the first param:
search(<collection>,
qt="/export",q="*:*",fl="display_material_number,display_pno,key_brand",sort="display_pno
asc",fq="searchmv_sales_org:(2106 OR 7950 OR 0)",
fq="-key_product_status:(INTERNAL OR WITHDRAWN)",
